Product Information

BLDC Controller

BLDC Controller

SEA, an eminent manufacturer of Process Control and Automation products indulge in providing BLDC Controller.
Detailed Description

1. Brushless DC (BLDC) Motors or electronically commutated motors (ECMs) provide significant improvements in efficiency, mechanical reliability, and offer superb torque-to-weight properties.

2.  All of which have become increasingly relevant in today’s environment where efficiency and minimizing power losses are essential objectives of designs in all markets.

3. How does BLDC motor work?

The permanent magnets are stationary, so they are called the stator. The armature rotates, so it is called the rotor. The armature contains an electromagnet. When you run electricity into this electromagnet, it creates a magnetic field in the armature that attracts and repels the magnets in the stator.

4. What is hall sensor in BLDC motor?

Bipolar Hall-effect sensors are used in BLDC motors to detect the position of the rotating magnet. In this example, an eight-pole motor with a three-phase winding uses three bipolar latching Hall-effect sensors. A magnetic field is required to activate a Hall-effect sensor.

5. The BLDC Motor speed is adjusted by varying the PWM duty cycle.

6. The feedback signal is getting from BLDC Motor by using a Hall Effect sensor.

7. The hardware of BLDC motor using a microcontroller is designed. By using the PWM technique speed of the BLDC motor was controlled and it was made to run at exactly entered speed.

 BLDC Motor Specification:

1. The BLDC Motor is highly reliable and having torque.

2. In industry, the BLDC motor is used widely.

3. The rotor part of the motor is rotated based on the stator excitation. 

4. The entire operation of the BLDC motor can be divided into 6 modes. Each mode has separated 60 degrees. All the Hall Sensors (A, B, C) are mounted at 120-degree phase shift. And will be HIGH for 180 degrees of 360-degree rotation.
